[OVMF] resource assignment fails for passthrough PCI GPU


dann frazier
 

Hi,
I'm trying to passthrough an Nvidia GPU to a q35 KVM guest, but UEFI
is failing to allocate resources for it. I have no issues if I boot w/
a legacy BIOS, and it works fine if I tell the linux guest to do the
allocation itself - but I'm looking for a way to make this work w/
OVMF by default.

I posted a debug log here:

Linux guest lspci output is also available for both seabios/OVMF boots here:
